Welcome to the latest in my series of using Docker in some fun and unusual ways. Previously I covered how to display a Matrix screen similar to the movie and showing a locomotive animation in your Docker session . This time, we’ll look an amazing telnet animation that’s been around for quite awhile (since 1997 according to this website). It shows the entire Star Wars Episode 4 movie using ASCII characters.

Welcome to the second in my series of using Docker in some fun and unusual ways. In the first installment, I showed how to display a Matrix screen similar to the movie.

Like last month’s this is an easy container to implement, consisting of only a three line Dockerfile.
By default CentOS 6 shows an animation while the system boots up, indicating its progress with either a rotating ring or a progress bar (in my experience physical machine installs show the rings, and VM installs show the progress bar). However, if you are from a sysadmin background or are responsible for monitoring one or more CentOS boxes, you may want to see what’s happening while the system comes up, rather than a simple animation.
If you are just starting working with Hadoop and Big Data, you may be at a loss for data to experiment with. Luckily, there is an abundant supply of freely available data sets on the Internet. Here I will highlight a few of the sources I have found out about, and I’ll add more as I find them.
